C＃ Comparison Operators
Comparison Operators
Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.
The return value of a comparison is either True or False. These values are known as Boolean values, and you will learn more about them in the Booleans and If..Else chapter.
In the following example, we use the greater than operator (>) to find out if 5 is greater than 3:
例子
int x = 5;
int y = 3;
Console.WriteLine(x > y); // returns True because 5 is greater than 3
A list of all comparison operators:
| Operator | Name | 例子 | Try it |
|---|---|---|---|
| == | Equal to | x == y | Try it » |
| != | Not equal | x != y | Try it » |
| > | Greater than | x > y | Try it » |
| < | Less than | x < y | Try it » |
| >= | Greater than or equal to | x >= y | Try it » |
| <= | Less than or equal to | x <= y | Try it » |
